A fork 69 for shifting clutch member 68 is pivoted on a pin I0 carried by a small bracket on bracket 56. The part ofthe fork '69 which extends below pivot I0 is in the form of a' lever II which extends downward and terminates at short distance above the bracket 38. A spring I2 acts to normally close the clutch connection cated at the point to which the lower end of the weight 45 arrives when said weight is at its highest position. weight is raised, the vertical arm 0114 rubs against the side of the weight until the lower I end of the weight arrives at notch I6, when the spring 15 throws .the notch under the weight to support it until released. I I

Faston the. rock shaft I3 is an arm I60 having axrollerl'l adapted tov engage a cam18 on the side of the lever H. When'the' weight is raised to a position which will permit the'spring I5 to move the bell crank lever 14, the roller 'l'l acts upon the cam I8 to, throw lever II from its full lineto dotted line position as shown in Fig. 8, and this action disconnects the clutch members ,On the side of: the weight I9 (Fig. l) which is engaged at all times by the pinion 560. TheIclutch6I-'68 serves to connect the pinion to or disconnect it from themotor.

,Pivoted ,on thebracket 38 is a. lever which has a pin 8| on its free end,'and a spring 82 act-- ing to elevate; it. When the weight. is' at its lower positionit engages the pin 8| to depress the lever" 80. to the position shown in Fig. 8. When, the weight is raised, the spring82 acts to lift the lever, but such lifting is temporarily restrained by the lower end of lever II. being over a shelf 83 on'said lever. When the weight reaches its highest position and permits spring I5 to operate thru roller I1 to move lever II to the right as shown in Fig. 8 and thusopen the clutch,.the lower end of lever -,I I passes fromthe shelf 83 and the spring 82 raises the lever 80 to bring the end of the shelf 83 behind the lever II and thushold-the clutch open. V ,The horizontal arm of the bell crank 1 4 hasa The-disk moves in the direction of the arrow'of Fig. 8, and the engagement. of the cam.88 serves tomove the notch 16 (from under the weight so that said weightv may fall. 1 Secured to the angleirons 39 and 40 near their lower ends is a pieceof insulation 81, on which its supported an electric switch'for controlling an electric circuit for the motor 55. Between the blades 880i this switch'is a bar .89, and pivoted to the center of this .bar isa link or'push rod 90. Enclosing the space between the brackets 31 and 33 is a casing 9I,.and supported in this casing directly opposite the end of the push rod is a push button 92.

The push-rod is guidedin a small bracket 93, and has on it a collar 94. Between the collar 94 and bracket 93 is a spring =which acts to .open the switch88. Beyond the;collar 94 therod Asya consequence, when the out compressingthe, spring 91.

46 is a'vertical rack 90 extends into the tubular stem 96 of the push button 92. The extreme end of the rod 90 is recessed, and in this recess is a spring 91 which is materially weaker than the spring 95. The spring 91 normally holds the collar 98 on stem 96 against the inner face of casing 9I, but will permit the push button to move inward without moving the switch 88. The proportions are such that while the inner face of the push button may strike the end of the push rod to move it inward, the amount of such movement before the button strikes the casing is not suificient to close the switch.

On one side of the push rod 90 is cut a slot or keyway 99, and in the stem 96 is a screw I00 having an end projecting into this keyway. This is a device for preventing the stem turning with .respect-to the push rod without interfering with the sliding of the stem on the rod. As shown in Figs. 9 and 12, there is a small recess in the rod opposite the end of the screw I00. This makes it possible to remove the. screw I00 and substitute a screw IOI as shown in Fig. 11. When changed to this arrangement, an inward push onthe button92 will close the switch 88 with- Thescrew I00 is inside'of the casing, and the change can only be madeflby removing the casing.

On-the side of the casing BI is an escutcheon I02 having a coin slot therein, and from this sloti a coin channel. I03 extends to the side of that part of the stem 96 which is within the casing. At the point where the coin would come when the button 92 is in normal position, a transverse slot is cut in the side of the stem to permit a coin rolling down channel I03 to project into a notch I04 cut in'the side of the push rod 90. Fig. 9 illustratesa coin I05 in this'position.

.With the'coin in this position, an inward push on the button 92 will cause the coin to act as a key to connect the stem 96 to the square shouldero'f the notch I04, and such push will move rod 90 inward to closethe electric switch. The opening H5 in the side of the coin chamiel permits the coin to pass'from the channel to a point over the coin bo-x I06.

Pivoted on the upperend of the bracket 93 is-a. hook. IO'Ladapted to engage the collar 94 on rod 90 when said rod is pushed in far enough to close the switch. This hook serves to retain the switch closed when the button 92 is released.

Upon such release, the spring 91 moves the. stem from the position shown in Fig. 10 to that shown in Fig. 9. This movement pulls the coin upward on the inclineof notch" I04 and ejects itso that it falls into the coin box.

On the side of the hook I0! is an arm I08 having its lower face inclined as shown in- Figs. 8 and 15. On theside of the lever II which faces away from the guide tube 4|, is pivoted an arm I09 having an incline to match the incline on arm I08. Theconstruction is such that when the lever 'II moves in the direction which opens the clutch 68, the pivoted arm I09 will ride over the arm I08, and when the lever II moves to close the clutch, the pivoted arm I09 will lift the hook I01 torelease the pushrod 90 and permit the spring to open the switch so as to stop the motor. f In. Fig. 11 is shown a way of connecting rod 90 to stem 96 so that the device may be operated without the use of a coin. Figs. 12, 13, and 14 show another way of. accomplishing the same resultbyusing a key lock I I0 inside of the button and stem 96 and setting the n device for that In normal position, the weight 46 is down,

and the bag 45 is in the dotted line position shown in Fig. 2. To bring the bag down to a position where it can be used, a coin is inserted in the slot, and the button 92 is pushed in. The coin makes a connection between the stem 96 and the rod 90 so that the inward push closes the electric circuit for the motor 55. The hook I 01 holds that position until released.

In normal position, the clutch is closed so that the motor, driving thru the worm gear 63 and pinion 65 raises the weight 46 from its lower to its upper position. As the weight and bag are on opposite ends of the rope, the raising of one lowers the other.

When the weight reaches the position shown in Fig. 6, the spring 15 acts on bell crank lever 14 to throw the notch 16 under the weight to prevent it from falling until released. The same movement of the bell crank lever causes the roller 11 to act on cam 18 so asto move lever H in a direction to open the clutch and'thus disconnect the lifting while the motor continues to lever H in a position to prevent the closing of the clutch until other things have been done. Also, the lever H carries the arm- I09 over the arm I68 to prepare for releasing the hook I01 so that spring 95 may open the electric switch which controls the motor.

The motor drives thru a worm toaworm gear on shaft 69, and a worm on shaft drives thru a worm gear to turnshaft 51. As a consequence, shaft 5! moves very slowly as compared to the speed of the motor. At the time the motor starts, the cam 86 is at the position shown in Fig. 8 and moves in the direction of the adjacent arrow. By the time the operations just described of raising the weight and lowering the bag have been completed, the cam 88 has advanced from the position shown in Fig. 8 to about the position shown in Fig. 6. From that time and until the cam has made acomplete revolution, nothing occurs in the mechanism, and it is during this period that the exerciser punches the bag.

When the cam has completed its circuit, it

moves bell crank lever 14 to release the weight,

which moves downward slowly and raises the bag at the same time. As the weight approaches its lowest position it engages pin 8| to release lever II and permit spring 12 to move that lever in the direction of closing the clutch; At the beginning of this movement, and before the clutchis closed, the arm 109 trips the hook I01, and this permits spring to break the circuit for the motor. This brings the parts back to their normal position ready to be started over again by the insertion of a coin and the pushing of the button.
